Filed: 1975-03-14
Abstract: 1486504 Temperature compensation FRITZ SCHWARZER GmbH 14 March 1975 [15 March 1974] 10868/75 Heading G1A [Also in Division G3]  A temperature compensated circuit include an electrical optical means for generating two signals, the sum of which is automatically regulated. As shown, for use in an ECG machine the positions of variable apertures 14, 15 (see also Fig. 2) are dependent upon a measured parameter of a patient. Light from LED's 12, 13 passes through the apertures 14, 15 on to photo-transistors 10, 11. Signals according to the incident light on those transistors are summed and compared in operational amplifier 29 with a reference from voltage divider 23, 24, 25 across a D.C. supply 20. Any difference varies the bias on transistor 33, in series with the LED's across the supply, so as to regulate the sum of the measured light intensities. The difference between the light received by phototransistors 10 and 11, which difference is dependant upon the position of the apertures 14, 15, is calculated by operational amplifier 40 to form an output that is recorded. If a rise in ambient temperature occurs, the currents through transistors 10, 11 increase and the bias on transistor 33 is thus reduced, so as to decrease the output of LEDs 12, 13 to effect temperature compensation. If LEDs 12, 13 are gallium arsenide and photo-transistors 10, 11 are silicon, these materials have opposite temperature coefficients and provide further temperature compensation.

Title: Improvements in or relating to the "scouring" of wool
IPC: C11B11/00
Filed: 1953-04-23
Abstract: In the process of the parent Specification, wherein wool grease is recovered from alkaline wool-scouring liquors containing an anionic detergent by adding thereto a minor proportion of a water-soluble ionizable salt not forming insoluble precipitates therein, the said salt comprising an alkali metal or ammonium salt of an organic acid containing less than 3 carbon atoms or of a mineral acid, heating the liquor until its colour darkens and a spot test of the liquor on filter paper gives an outside clean ring with a dark centre and then separating the wool grease from the liquor by centrifuging, the liquor is allowed to stand after the heat treatment for at least 4 hours before it is centrifuged to separate the grease therefrom. During the standing the moisture in the grease is reduced and some of the heavy metal salts settle out, thus causing less pollution of rivers to which the discarded liquor is fed.  Standing periods of up to 65 hours may be used.  The process of the parent Specification may be further modified by allowing the scouring liquors to stand and then subjecting them to a preliminary centrifuging operation to remove any separable grease, these operations being effected before the addition of the ionizable salt.  A higher quality grease fraction is obtained.  The standing period may be similar to the above.
